Description
June 11, 1940. HUGHES 2,204,084
JOCKEY PULLEY Filed June 24, 1938 Patented June 11, 1940 UNITED STATES PATENT OFFICE JOCKEY PULLEY John Hughes, Rochdale, England Application June 24, 1938, Serial No. 215,648 In Great Britain June 26, 1937 3 Claims.
This invention relates to improvements in jockey pulley assemblies, particularly for use in textile frames, e. g., for engagement with a tape driven by a tin roller in a spinning or twisting frame.
idly together.
Description will now be given of a jockey pulley assembly constructed according to the invention, reference being made to the accompanying drawing in which Fig. 1 is an axial section of a jockey pulley assembly and Figs. 2 and 3 are fragmentary sectional views of modifications later to be described.
Referring to Fig. 1,
l indicates the pulley proper of dished form attached to a hollow hub 2 accommodating a ball bearing 3 the outer race 4 of which is secured within the hub 2 for rotation therewith, and the inner race 5 of which is secured on a stub-shaft 6 terminating within the hub and extending exteriorly of the pulley through the rear end of the hub. The outer race 4 is interposed endwise between an annular abutment shoulder 1 formed in the hub 2 and an annular nut 8 screw-threaded into the rear end of the hub. The inner race 5 is interposed endwise between'a collar 9 on the inner end of the shaft 6 and a spacer tube I0 surrounding the shaft 6. The shaft 6 is secured exteriorly of the pulley in a boss ll of a pulley-supporting bracket-arm I2 by a nut l3 screw-threaded on the outer end of the shaft 6 and abutting, with the interposition of a washer 14, on the boss ll. l5 denotes a pulley dust cover strung on the shaft and interposed between the boss H and the spacer tube I0.
As will be understood, the construction is such that the components 5, 6, [0, H and I5 are clamped solidly together by the pressure exercised by the nut IS.
I6 to secure the parts firmly together.
The
bush I5 is formed integrally with a lubricating nipple l6" which is engageable by a lubricant gun or the like for the purpose of injecting lubricant for the ball bearing into the interior of the hub. 5
According to a modification, instead of being integral with the bush IS, the lubricating nipple may be separate, and, as shown in Fig. 2, the bush Hi is formed with a cylindrical bore I6 serving as a socket for the reception of the '10 spigot ll of a lubricating nipple I8; or the lubricating nipple I8 may be screw-threaded to engage a screw-threaded part in said bush.
In the further modification illustrated in Fig.
3 the pulley proper is provided on its periphery 16 with a centrally disposed rib l witha cambered surface I", I respectively on either side of said rib, the construction being adapted to keep the driving tape running in the correct position. The central rib enables the jockey pulley to be :0 run in either direction and the position of the tape is controlled, thus preventing it from slipping oif when the pulley is reversed for warp or weft way.
Manifestly, the construction is such that the g5 pulley may be assembled or dismantled with the minimum of labour and skill, and the components are all of simple design so that replacements will be readily obtainable.
I claim:
1. A jockey pulley assembly adapted 'to be attached to a supporting bracket, and including, in combination, a pulley proper of dished form having an integral web, a hollow hub formed separately from and rotatable with said pulley proper, said hub housed within said pulley proper with its inner face abutting on the inner face of said web, a combined flanged bush and lubricating nipple axially penetrating said web and the adjacent end of said hub, said bush having a 40 flange abutting on the outer base of said web and the inner end of said bush being pressed over to engage said hub, whereby to secure firmly together said pulley proper and said hub, a stubshaft terminating within said hub, an inner bearing race removably held on said shaft, an outer bearing race, means engaging said hub removably holding said outer race within said hub, anti-friction bearing elements accommodated between said races, a spacer tube surrounding said shaft and adapted to abut at its inner end on said inner race, a dust cover strung on said shaft and interposed between said bracket and said spacer tube, and a nut on the outer end of said shaft for clamping solidly together said shaft, said inner race, said spacer tube, said dust 3. Jockey pulley assembly as claimed in claim cover, and said bracket. 1 in which the pulley proper is provided on its 2. A jockey pulley assembly as claimed in periphery with a centrally located rib and with claim 1 in which the outer race is solidlyheld a cambered surface on each side of said crib.
against a shoulder on the hub by means of a removable nut screw-threaded into the bore of JOHN HUGHES.
the hub with its inner end abutting against the outer race.
